Energy Star, a US-led energy-saving program focused on consumer electronics. The Energy Star program was launched in 1992 by the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE) to reduce energy consumption and reduce greenhouse gas emissions. The plan was later adopted by Australia, Canada, Japan, Taiwan, New Zealand and the European Union. The program is voluntary and ENERGY STAR standards are typically 20-30% more energy efficient than US federal standards. The earliest products with this program is mainly computer and other information appliances, and then gradually extended to the motor, office equipment, lighting, home appliances and so on. The US Environmental Protection Agency (EPD) has been actively promoting the Energy Star Building Program since 1996. The Environmental Protection Agency (EPD) assists voluntary industry participants to assess the energy use of their buildings (including lighting, air conditioning, office equipment, etc.) and plan the building Energy efficiency improvement action plan and follow-up operation, so some of the introduction of new concepts of environmental protection in the home or industrial and commercial buildings can also be found in the Energy Star logo.

To carry out the status quo

Canada, Japan, Taiwan, Australia, New Zealand, the European Union and the International Energy Star Program since 2001. The Energy Star Program has been launched by the US Environmental Protection Agency (EPA) in seven countries and regions. There are more than 30 kinds of products, such as household appliances, heating / cooling equipment, electronic products, lighting products and so on, which are now included in the scope of certification. Currently, most products in the Chinese market are lighting products, including CFL, , Lamps (RLF), traffic lights and exit lights.

(EPA) and the US Department of Energy (DOE) announced on April 14, 2010 that they will adjust the Energy Star certification process to ensure that only qualified products are eligible for the ENERGY STAR label. In this adjustment, the immediate entry into force of the terms: the manufacturer in order to obtain the "Energy Star" certification label, must submit a complete test report and assessment results by the EPA to prove that the EPA approval of the product as "energy Star "qualified products, manufacturers will not be able to get" Energy Star "certification mark. At the same time, in the Energy Star certification review process, EPA strengthened the approval system, no longer rely on automatic approval process, but all of the new eligibility applications for examination and approval.

The EPA and DOE will further strengthen the ENERGY STAR certification program by the end of 2010, requiring all manufacturers to submit test results from accredited, accredited laboratories to ensure that they meet ENERGY STAR requirements. The products covered are windows, doors, skylights and fluorescent light bulbs. In the new testing process, more than 60 product categories under the ENERGY STAR program will be expanded to include freezers, freezers, , Washing machines, dishwashers, water heaters and room air conditioners.

Energy Star Housing Program

The EPA's Energy Star Housing Program is a nationwide voluntary program designed to build a new 30-percent energy-efficient house. Qualified ENERGY STAR residences are subject to a third party verification to confirm that the energy efficiency measures have been appropriately adopted by the manufacturer. As long as you can see the ENERGY STAR logo, the home buyer is not an expert and can make a purchase decision with great confidence. In general, ENERGY STAR is 30% less energy efficient than a general-purpose energy source, while protecting the environment and conserving energy for the household. Energy Star residential construction is not only beneficial to buyers, but also conducive to builders, mortgage companies and other industries in the housing industry, so the nation's residential builders are to support the Energy Star residential program.

Homes are usually new homes because it is much simpler to build a house that complies with the energy saving rules than renovating a built house. Although the cost of upgrading the housing to get the ENERGY STAR logo is high, but it can significantly reduce energy use costs, so the energy-saving renovation of existing homes is still a good idea. When replacing air conditioning, electrical, or lighting equipment, consider purchasing energy-starved products that can further improve the energy efficiency of your home.

The ENERGY STAR residential program uses the Residential Energy Evaluation System (HERS) to determine the residential energy efficiency score. New and existing homes are required to meet the same energy efficiency standards for the ENERGY STAR logo. In order to obtain a HERS assessment or to find a way to obtain the ENERGY STAR logo, consult with a locally assessed residential energy assessment agency that compares the model house with the same size and shape as the assessed house and that meets the energy specification minimum Requirements), HERS evaluation system for the residential energy efficiency objective and standard evaluation. The HERS assessment score is between 0 and 100. The score of the model house is 80 points. Compared to model homes, every 5% reduction in energy consumption equals a one point increase in HERS. The lowest HERS rating for ENERGY STAR residences is 86. The HERS assessment includes on-site testing of the house. The tests include blower door testing and pipeline leak testing. The results of these tests, along with other information about the house, are entered into a simulated computer program to calculate the HERS score and estimate the annual energy costs.

Energy-saving windows use

Energy Star residential installation of high-performance energy-saving windows, improve residential energy efficiency. Multi-layer glass and sealed window frames block external noise; Prevents curtains, furniture and flooring from fading - Energy-efficient windows are covered with a low-reflectance coating that blocks 98% of the UV light; Reduces operating costs - - Energy-saving windows reduce heat dissipation in the winter and prevent heat absorption in the summer; Quality improvement - Energy-saving windows are made of high-quality materials and are easy to use and provide additional protection for the user. The windows take up about 10-25% of the house's exterior wall area. Depending on the climate, it takes 25-50% of the energy when the room is heated and cooled. Therefore, when a new house, consider the use of energy-saving windows is essential.

Heating and cooling equipment

ENERGY STAR houses are equipped with suitable power and efficient heating and cooling equipment. In the residential construction process, heating and cooling equipment in ENERGY STAR residences is usually less powerful than residential buildings built in accordance with general energy codes, with due attention to air duct sealing, residential insulation and energy-saving windows.

Reduce the use of cost - heating and cooling equipment does not require overload;

Reduce maintenance problems - heating and cooling equipment always in the optimal state of operation;

Quieter home environments - do not have to constantly, frequently switch on the ultra-high-power equipment.

The lack of air and ventilation ducts means that heating and cooling equipment in an ordinary house needs to increase its power to quickly meet its requirements for heat and cold. But this high-power equipment, there are great shortcomings ① can not run for a long time to achieve its most efficient level of operation; ② when the system can not run for a long time to exclude moisture in the air, it led to housing damp problems; ③ high-power devices are often as a result of frequent start-up equipment quickly paralyzed. Tight air and ventilation ducts reduce the need for residential air-conditioning gas heating and cooling, so you can avoid the use of high-power equipment.

Thermal insulation performance

Compared to buildings built according to common energy specifications, ENERGY STAR residential insulation has been significantly improved. The increase in thermal insulation not only prevents excessive hot and cold spillage, but also maintains a constant temperature between the rooms.

Increased comfort - Constant temperature is maintained throughout the house and between rooms.

Reduced operating costs - The HAVC device compensates for a small amount of hot and cold heat exchange in the winter and summer.

In order to effectively maintain the temperature of the house, indoor and outdoor continuous insulation layer is necessary. The laying of the insulation must be free of cracks, curl or compression. ENERGY STAR residences must also pay attention to insulation measures around obstructions such as pipelines, electrical wiring, and exits.

Sealed

Sealed Conduit Energy star housing has a much higher sealing requirement for ducts than residential buildings built in accordance with common energy specifications. Sealed ducts are essential to conserve energy and maintain home comfort.

More continuous comfort - allocated for each room.

Significantly improves indoor air quality - Reduces room intake of dust and other contaminants from the outside world.

Reduce the cost of use - to reduce the room for air-conditioning gas needs. In typical US homes, the air leaks from the ducts reach 20-30%, which means that you spend a lot of unnecessary money to make the room warm or cool. The conduit system should remain sealed and partially tested to reduce the leakage of air conditioning gas.

Energy Saving

Owners of existing homes can use the Internet-based assessment tool, the Energy Star Residential Benchmark, to compare annual residential energy consumption with similar homes in the country. This tool helps owners of completed homes understand whether their homes meet energy efficiency requirements and whether residential energy efficiency measures should be upgraded to improve energy efficiency. On the ENERGY STAR website, this tool also helps owners of completed homes to quickly decide which home-improvement option to improve energy efficiency.

The ENERGY STAR Housing Program also provides a "housing retrofit kit" to help energy-efficient homes that have already been built. The average family's annual energy use expenditure is 1,400. The "Housing Transformation Toolbox" helps reduce these expenditures by 30%, almost 400%. When rebuilding, rebuilding, or improving a built-up house, the energy saving measures in the "Housing Modification Toolbox" Can help homeowners improve the energy efficiency, value and comfort of their homes, and protect the environment by reducing energy consumption. For homeowners, the "Housing Transformation Toolbox" makes it easier to retrofit and repair homes.
